Both (!) of my girls have had to have surgery to remove bladder stones. I asked their vet for a recipe that I can make for them that I could make instead of buying the high priced prescription dog food. This is the recipe she gave me. This recipe is for the daily feed of a 40 pound dog. I wasn't able to add two ingredients to the list so please see the directions! This freezes very well. I make enough for the week, freeze it in microwavable containers defrost/heat as needed. Both of my girls love this I'm so lucky that my (their) vet was able to find this recipe for us!
